SDO scale (Social Dominance Orientation)

Social Dominance Orientation (SDO) is a measure of an individual's preference for hierarchy and inequality among social groups. People with high SDO tend to support systems that favor their group’s dominance over others, often accepting or endorsing social inequalities. Conversely, those with low SDO prefer egalitarian relationships, valuing equality across groups. The SDO scale helps researchers understand attitudes toward social hierarchy, power, and inequality, and how these beliefs influence behaviors and policy preferences related to social justice and group relations.
